They are completely different kits of course. As far as I know the Xtreme Composite one is identical to the Naruke Hobby version i.e. Onda's (except it's all composite, not wood). The Oxai Astrals have a solid canopy and a different colour scheme on the bottom. The new Oxai XX may be identical but the Oxai Astral X wasn't.

As for me well I'm definitely going for the Xtreme Composite one. It even has the tank and carbon rod elevator push-rod installed for you! Pre drilled for Hyde mount etc etc. Just drop your gear in and off you go.

When I get a web address for Xtreme or Emerald Hobby I will post it here.
